What are possible symptoms?

Most people with diverticulosis will not have symptoms. However, symptoms can occur if inflammation is present (i.e., diverticulitis).  Diverticulitis occurs when there is high pressure in the large intestines or if hardened stools become stuck in the diverticulum causing inflammation or infection.

Symptoms of diverticulitis may include: constipation, nausea, vomiting, diarrhea, painless bleeding from rectum, abdominal pain, fever, bloating, pain or frequent urination.

What are possible treatments?

There is no treatment for diverticulosis, the goal is to prevent inflammation (i.e., diverticulitis). If diverticulitis occurs treatment will vary based on the severity of the condition therefore it is important to seek medical guidance.
